Serial Write

Write data to serial port

Since R2020b

Libraries:
NVIDIA Jetson and NVIDIA DRIVE / Communication

Description

Use the Serial Write block to write data to a serial device connected to a NVIDIA^® Jetson™ hardware. To open the serial pin map of the NVIDIA Jetson board, click the View pin map button. For more information, see .

Examples

Read and Write Data over Serial Port on NVIDIA Jetson Platforms

Use MATLAB® Coder™ Support Package for NVIDIA® Jetson® and NVIDIA DRIVE® to read and write serial data over the UART port on a Jetson board.

Port_1 — Input port that accepts data
[Nx1] or [1xN] array

The input port through which the block accepts data.

Parameters

expand all

Port — Port at which you connect board to serial device
`/dev/ttyTHS1` (default)

The port at which you connect the NVIDIA Jetson board to the serial device.

Baudrate (in bits/s) — Bits per second
`9600` (default) | `50` | `75` | `110` | `134` | `150` | `200` | `300` | `600` | `1200` | `1800` | `2400` | `4800` | `19200` | `38400` | `57600` | `115200` | `230400`

Select the rate at which the data is read over the serial line. The baud rate is measured as the number of bits read per second.

Parity — Parity added to data to detect error
`None` (default) | `Even` | `Odd`

Select the parity you want to add to the transmitted data. A parity bit is used to detect error in the data transmission.

None – This value means that no parity is used for error detection in the data transmission.
Even – The parity bit value is 1 if the number of bits with value 1 is odd. The parity bit value is 0 if the number of bits with value 1 is even.
Odd – The parity bit value is 1 if the number of bits with value 1 is even. The parity bit value is 0 if the number of bits with value 1 is odd.

Stop bits — Bits used to signal stop of data transmission
1 (default) | 2

Select the number of bits used to signal the stop of data transmission.
